AN ORAL HYGIENE DEVICE

FIELD OF THE INVENTION

The present invention broadly relates to an oral hygiene device. More specifically but not exclusively the present invention relates to a combination toothbrush and paste storage device.

BACKGROUND

There are a large variety of oral hygiene devices available today for performing a variety of oral hygiene functions such as cleaning and refreshing.

One such common device is a toothbrush. Toothbrushes traditionally consist of a body portion suitable for being held by a user, and at least one brush portion suitable for cleaning, brushing, scrubbing, disinfecting, refreshing, wiping, massaging or picking (herein after referred to as "cleaning") any one or more of a person's teeth, gums or other surfaces located within a person's mouth or throat.

It is common to use a toothbrush(s) in conjunction with a paste, gel or liquid (herein after referred to as "paste(s)") to facilitate the cleaning of a users mouth. The paste is commonly supplied independently in a tube or similar container.

Through prolonged use parts of many oral hygiene devices tend to wear out. For example the brush portion(s) of a toothbrush tend to wear out making them less effective for their intended purpose. It is also common to dispose of the entire oral hygiene device once it has worn out and replace it with a new one. It would be beneficial to replace only the worn out portions of the oral hygiene device to save in material wastage and costs.

Whilst toothbrushes and other oral hygiene devices are normally stored in a users residence (such as in a bathroom/washroom), in some situations it is desirable to carry a toothbrush or similar oral hygiene device to another location. For instance when a person is travelling to another destination where they may have a need for an oral hygiene device or for users that have an unexpected need for an oral hygiene device and have chosen to carry such a device on their person in case of such an event. In these situations carrying an oral hygiene device and/or paste in a bag or on the person would be required. It is important to keep both paste and oral hygiene devices clean, specifically; any parts of an oral hygiene device that would normally come in contact with the mouth or throat during use should preferably not come in contact with anything that could contaminate the device. In this sense, most oral hygiene devices (such as toothbrushes) need to be protected in some way when being carried in a bag or on the person.

As it is common to use an oral hygiene device in conjunction with paste it is also desirable that both items can be kept together. In most situations these two items are separate which is convenient for use but can make locating them individually difficult, especially in a person's handbag or toilet bag. Likewise floss string may be carried separately by a person.

It would therefore be an advantage to provide improvements to an oral hygiene device that addresses or goes at least some way towards addressing at least some of the abovementioned disadvantages and/or addresses at least some of the

abovementioned advantages or that will at least provide the public or industry or both with a useful choice.

DETAILED DESCRIPTION OF THE DRAWINGS

The present invention is for an oral hygiene device. In the most preferred embodiment the present invention is a toothbrush suitable for cleaning a user's teeth. Alternative embodiments could include other features for use as oral hygiene devices such as flossing tools and polishing tools.

The toothbrush 101 in the preferred embodiment includes a brush head 10, a housing 20, a container 30 and a fluid dispenser 40.

The brush head 10 of the preferred embodiment comprises a plurality of bristles 11 supported by a bristle support member 12. The brush head 10 is mounted on a head support member 50 that is in turn pivotally coupled to the housing 20. The housing 20 in the preferred embodiment includes an opening or recess 21 (herein after referred to as "recess") that is configured to at least in part receive the brush head 10.

The head support member 50 in a preferred embodiment can be pivoted about the pivot axis 51 such that the brush head 10 can be moved from a stowed condition as shown in figures 2A and 2B to a presented condition as shown in figures 1A and IB.

Whilst the preferred embodiment of the invention is shown in figures 1A, IB, 2A and 2B it will be appreciated that any other mechanisms could be used to move the brush head 10 to and from a condition where it is stowed and substantially enclosed within the recess 21 to a condition where it is presented for use. Other such mechanisms could include but are not limited to, a head support member 50 that twists relative to the housing 20, a head support member 50 that slides relative to the housing 20, a head support member 50 that translates relative to the housing 20, or a head support member 50 that rotates relative to the housing 20.

In the preferred embodiment the head support member 50 is configured such that when in the stowed condition it complements the shape and configuration of the housing 20 to form a substantially continuous external surface. This can be seen in figures 2A and 2B. In the preferred embodiment in the stowed condition the housing 20 and head support member 50 retain a substantially constant cross sectional shape. Furthermore in the preferred embodiment the housing and head support member 50 in the stowed condition are substantially elongate.

Also clearly shown in figures 2A and 2B is the brush head 10 wholly enclosed within the recess 21 of the housing 20. In an alternative embodiment only the bristles 11 of the brush head 10 may be substantially enclosed in the recess 21 when in the stowed condition.

In another alternative embodiment the brush head 10 is only partially enclosed within the recess 21 when in the stowed condition.

In a preferred embodiment of the invention, the head support member 50 is connected to the housing 10 via a linkage 60. The linkage 60 in the preferred embodiment includes an activation slide member 62 and at least one load bearing arm 61. The activation slide member 62 in the preferred embodiment is mounted on the housing 20 such that it can slide forward and backward along an axis. The load bearing arm 61 is mounted to the activation slide member 62 and to the head support member 50 such that when the activation slide member 62 is moved backward and forwards along its axis it subsequently causes the head support member 50 to move between the stowed condition and the presented position and vice versa.

The brush head 10 in a preferred embodiment is removable from the oral hygiene device 100. In a preferred embodiment the bristle support 12 is configured to be selectively engaged and disengaged with the head support member 50. This is intended to allow the brush head 10 to be replaced individually of the other components of the oral hygiene device 100.

In the preferred embodiment the brush head is configured to connect with the support head member 50 via a snap or press fit coupling such as that shown in figures 5 or 6. The coupling 70 shown in figures 5 and 6 includes a retaining protrusion 71 and a complementary receiving slot 72. In the embodiment shown the retaining protrusion 71 is profiled in a T-shape, but it will be appreciated that any cross sectional profile and receiving slot with a complementary shape could be used.

In the preferred embodiment the coupling 70 is configured to create interference between the retraining protrusion 71 and the complementary receiving slot 72 in a press fit arrangement. Alternatively the coupling includes deformable or displaceable retaining lugs or the like suitable for creating a snap fit configuration between the brush head 10 and the head support member 50.

Alternative embodiments to this could also include connecting the brush head 10 to the head support member 50 using complementary threaded sections on each component allowing them to screw together.

Another alternative embodiment for connecting the brush head 10 to the head support member 50 includes using a bayonet coupling to connect them.

In the preferred embodiment the fluid dispenser 40 can dispense a fluid 80. In the preferred embodiment the fluid dispenser 40 includes a fluid outlet 41 and a dispensing mechanism 42 that allows a finite amount of fluid to be dispensed at any one time. In the preferred embodiment the fluid is toothpaste or the like, however, it will be appreciated that any Newtonian or non-Newtonian fluids such as pastes, gels, creams or liquids could be used. In the preferred embodiment the fluid dispenser 40 is configured to be either cheap to manufacture or easy to refill. This allows the fluid dispenser to either be re-used or to be disposed of due to its low cost to replace.

In the preferred embodiment the container 30 is configured to at least in part receive the fluid dispenser 40 and can be selectively engaged and disengaged with the housing 20. In the preferred embodiment the fluid dispenser is wholly contained within the container 30 when it is engaged with the housing 20 and prevents any fluid from being dispensed.

Alternatively a portion of the fluid dispenser is always accessible to allow fluid to be dispensed .

When engaged with the housing 20 the container 30, in the preferred

embodiment is configured to at least in part form a handle 31 to be gripped by a user when the oral hygiene device 100 is in use.

In a preferred embodiment the container 30 is engaged with the housing via a bayonet coupling.

Alternatively the container 30 is engaged with the housing 20 via complementary threaded sections on each component allowing them to screw together. In another alternative embodiment the container 30 is engaged with the housing 20 via a press or snap fit coupling.

In a preferred embodiment when the brush head 10 is in the stowed condition and when the container 30 is engaged with the housing 20 the oral hygiene device 100 has a substantially uniform external surface. In the preferred embodiment the cross section of the oral hygiene device is substantially constant. The container and housing are in the preferred embodiment elongate and inline.

In this preferred embodiment the housing 20 and the container 30 in

combination, at least in part form a handle 31 suitable for being griped by a user when the oral hygiene device is being used.

In a preferred embodiment the external shapes of the container and the housing complement each other such that the oral hygiene device appears substantially uniform and has a substantially continuous outer surface.

The oral hygiene device may have incorporated therewith a dental floss dispenser 200. This is for example shown in Figures 7 and 8. In one form the dispenser 200 may be integrally formed as part of the oral hygiene device or may alternatively comprise of a an accessory that can be attached to for example, the housing 20 or more preferably to the container 30 as for example shown in Figure 7. The dispenser 200, if engaged to for example the container 30, may be of a similar diameter or perimeter shape as the container 30. The dispenser is preferably of a circular shape commensurate with that of the shape of the container 30. This allows for the dispenser to integrate as part of the oral hygiene device in a clean and aesthetic manner. The dispenser preferably houses floss string or ribbon 201 the tail end of which is visible in Figure 8. In Figure 8 it can be seen that as part of the dispenser a removable cover 204 is provided. The removable cover 204 may for example hinge relative to the housing portion 205 of the dispenser so as to be able to move between a floss string exposing condition as shown in Figure 8 and a floss string covering condition as shown in Figure 7. The housing 205 may also carry a knife 206. This knife 206 can be used to sever the tail end of the floss string from the dispenser so that the floss string can then be used by a person to clean their teeth and gums. The tail end of the floss string is able to be exposed to the outside of the dispenser by passage through the aperture 207 of the housing 205. Within the housing 205 the floss string may be located on or itself define a bobbin 208 located within the housing 205 of the floss string dispenser. The floss string bobbin may be supported on an axle 209 as shown in Figure 17. It can be internally supported on the axle 209 so as to allow for it to be rotated about a longitudinal axis for the purposes of facilitating the dispensing of string from the dispenser. The floss sting bobbin 208 may be of a kind that can allow for it to be provided in a consumable and replacement form. A cap 210 may be provided that is removable from the housing 205 so as to expose the internals of the housing 205 so that a new bobbin can be loaded therein for subsequent use. The cap 210 may be removably engaged to the housing 205. The cap 210 may be the cap that in another mode of use of the present invention is used to close the container 30 as for example shown in Figure 18. The cap 210 closing the container 30 is able to be removed from the container as shown in Figure 19 and then aligned with the dispenser 200 when a dispenser is desired to be engaged to the container 30. The container 30 may include fastening features at its end that are complimentary with both the dispenser 200 as well as the end cap 210. The end 211 of the dispenser 200 is preferably designed to be complimentary with the end cap 210 so that the end cap 210 can be received thereat for closing the housing portion 205 of the dispenser. Such a close condition is for example shown in Figures 21 and 22. A person can open the cover 204 to expose the tail end of the floss string 201 and allow for the floss string to be drawn at least in part out from the housing 205. The knife 206 can be used to cut the floss string so that the floss string can be used by a person. When the dispenser is fully discharged and no more string is available for a user to remove therefrom the entire dispenser 200 may be discarded and replaced with a new dispenser. Alternatively it may just be the bobbin 208 that is replaced, keeping the housing 204 in place. As can be seen the dispenser provides the ability to have an add on accessory to the oral hygiene device of the present invention.
